Annual Inspection requires which of the following?

• A. Every aircraft
• B. 12 calendar months
• C. A&P with IA
• D. Not overflown

Answer: (C)

An Annual Inspection must be performed by an A&P mechanic who holds an Inspection Authorization. This credential guarantees the inspector has the training and authority to conduct the thorough, sign-off required for airworthiness under the applicable regulations. The inspection is required at intervals not exceeding 12 calendar months, but the defining requirement is who performs it: an A&P with IA. The other statements don’t capture this essential point—the timing is a factor, but the key requirement is the authorized inspector.
